To aZZ whom t may concern;

Beit known that I, Helma' B. SAUERMAN, e citizen of the United States, residing? at hicago, in the county o Cook of ois, Improvement in` Excavating Apparatus, of is a specification.

y invention relates, more: particularly, to excavating apparatus, of the type employ ing scraper-buckets, in which. 'the bottom of the scraper is connected Witiivthe' body ortiou thereof in e manner tcpermit the bottom to swing relative tc lsaioi body-portion to a position in which the load-is dumped.

The bottom of the scraper represented at 26 and is'shovvn es couuectezi with the plates 25 au with upright levers 27 und isprovided with the cutting edge 261. The section 21 is provided `with e pair of upwardly vand `forwardly projecting bars 28 which extend forwardly ybeyond the sc er at opposite sides thereof as shown, aufi t ese bars, the outer ends of which are ir-u fiected at 29, the levers 27 are pivoteci iw tween their ends, as indicated at 30, the. parts being' so arranged that when in v position of the parts, viz., that shown iu if i, the buclretwiil be closed at its sides ani. lbottom as shown in thisigure.
